This notice includes all models — even kids and city bikes — built from 2000 to 2015. The danger stems from a quick-release lever on the front wheel. The mechanism can come into contact with the brake assembly, causing the wheel to separate or come to an instant stop.

Of the three incidents reported, one person suffered face injuries, another a fractured wrist, and the last person is now a permanent quadriplegic. Trek recommends consumers immediately stop use and contact an authorized retailer for a free installation of a new lever.
